2009-06-22ALSA: ctxfi - Add PM supportWai Yew CHAY
Added the suspend/resume support to ctxfi driver. The team tested on the following seems ok: AMD Athlon 64 3500+ / ASUS A8N-E / 512MB DDR ATI / Radeon X1300 20k1 & 20k2 cards Signed-off-by: Wai Yew CHAY <wychay@ctl.creative.com> Singed-off-by: Ryan RICHARDS <ryan_richards@creativelabs.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-22ALSA: ctxfi - Allow unknown PCI SSIDsTakashi Iwai
Allow unknown PCI SSIDs for emu20k1 and emu20k2 as "unknown" model. Also, add a black-list check in case any device has to be listed as "unsupported". It has a negative value in the pci quirk entry. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-15ALSA: ctxfi - Fix deadlock with xfi-timerTakashi Iwai
The PCM x-fi native update routine can cause deadlocks when the trigger(START) is called while the stream is running. This patch fixes the deadlock by just postponing the pcm period update to the next possible wake-up. Also it adds the flip of ti->running flag (just to be sure as now). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-13ALSA: ctxfi - Replace atc lock to mutexTakashi Iwai
The spinlock in atc can cause a sleep in lock: Kernel failure message 1: BUG: sleeping function called from invalid context at mm/slub.c:1599 in_atomic(): 0, irqs_disabled(): 1, pid: 2537, name: gstreamer-prope Pid: 2537, comm: gstreamer-prope Tainted: P 2.6.29.4-167.fc11.x86_64 #1 Call Trace: [<ffffffff8103ff0f>] __might_sleep+0x10b/0x110 [<ffffffff810cd734>] __kmalloc+0x73/0x130 [<ffffffffa0b4b142>] ? daio_rsc_init+0xaa/0x125 [snd_ctxfi] [<ffffffffa0b4b212>] dao_rsc_init+0x55/0x1c0 [snd_ctxfi] [<ffffffffa0b4b3d2>] dao_rsc_reinit+0x55/0x5d [snd_ctxfi] [<ffffffff813abd6c>] ? _spin_lock_irqsave+0x32/0x3b [<ffffffffa0b454fe>] atc_spdif_out_passthru+0x92/0x136 [snd_ctxfi] ... Since the lock path is no critical path, it can be gracefully replaced with a mutex. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-09ALSA: ctxfi - Clear PCM resources at hw_params and hw_freeTakashi Iwai
Currently the PCM resources are allocated only once and ever in prepare callback, assuming that the PCM parameters are never changed. But it's not true. This patch adds the call of atc->pcm_release_resources() at hw_params and hw_free callbacks to assure that the PCM setup is done correctly for each h/w parameter changes. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-09ALSA: ctxfi - Check the presence of SRC instance in PCM pointer callbacksTakashi Iwai
The SRC instances may not exist when PCM pointer callback is called at the state before initialization is finished. Add the NULL check just to be sure. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Add use_system_timer module optionTakashi Iwai
Added use_system_timer module option to force to use the system timer instead of emu20k1 timer irq for debugging. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Fix wrong model id for UAATakashi Iwai
CTUAA should be checked instead of CTHENDRIX. The latter is for 20k2 chip. Also, fixed the detection of UAA/HENDRIX models by fixing the mask bits. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Clean up probe routinesTakashi Iwai
Clean up probe routines and model detection routines so that the driver won't call and check the PCI subsystem id at each time. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Fix / clean up hw20k2 chip codeTakashi Iwai
- Clean up Hungarian coding style - Don't use static variables for I2C information; this unables to use multiple instances. Now they are stored in struct hw20k2 fields. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Fix possible buffer pointer overrunTakashi Iwai
Fix possible buffer pointer overruns. Back to zero when it's equal or over the buffer size. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Remove useless initializations and castTakashi Iwai

2009-06-08ALSA: ctxfi - Fix DMA mask for emu20k2 chipTakashi Iwai
Allow 64bit DMA mask for emu20k2 chip, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Make volume controls more intuitiveTakashi Iwai
Change the volume control to dB scale (as the raw data seems so). Also added the TLV dB-scale information. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-08ALSA: ctxfi - Optimize the native timer handling using wc counterTakashi Iwai
Optimize the timer update routine to look up wall clock once instead of checking the position of each stream at each timer update. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-06-05ALSA: ctxfi - Set device 0 for mixer control elementsTakashi Iwai
Mixer control elements are usually assigned to device 0. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Clean up / optimizeTakashi Iwai
- Use static tables instead of assigining each funciton pointer - Add __devinit* to appropriate places; pcm, mixer and timer cannot be marked because they are kept in the function table that lives long - Move create_alsa_devs function out of struct ct_atc to mark it __devinit Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Set periods_min to 2Takashi Iwai
Set 2 to minimal periods of playback pcm setups, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Use native timer interrupt on emu20k1Takashi Iwai
emu20k1 has a native timer interrupt based on the audio clock, which is more accurate than the system timer (from the synchronization POV). This patch adds the code to handle this with multiple streams. The system timer is still used on emu20k2, and can be used also for emu20k1 easily by changing USE_SYSTEM_TIMER to 1 in cttimer.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Fix previous fix for 64bit DMATakashi Iwai
Remove unneeded substitution to 32bit int to make it really working. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Fix endian-dependent codesTakashi Iwai
The UAA-mode check in hwct20k1.c is implemented with the endian-dependent codes. Fix to be more portable (and readable). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-05ALSA: ctxfi - Allow 64bit DMATakashi Iwai
emu20kx chips support 64bit address PTE. Allow the DMA bit mask to accept 64bit address, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-06-02ALSA: ctxfi - Support SG-buffersTakashi Iwai
Use SG-buffers instead of contiguous pages. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Remove PAGE_SIZE limitationTakashi Iwai
Remove the limitation of PAGE_SIZE to be 4k by defining the own page size and macros for 4k. 8kb page size could be natively supported, but it's disabled right now for simplicity. Also, clean up using upper_32_bits() macro. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Fix supported PCM formatsTakashi Iwai
The device seems supporting only U8, S16, S24_3LE, S32. Other linear formats result in bad outputs. Also, added the support for 32bit float format, which wasn't listed in the original code. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Fix PCM device namingTakashi Iwai
PCM names for surround streams should be also fixed as well as the mixer element names. Also, a bit clean up for PCM name setup. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Fix surround mixer namesTakashi Iwai
We usually pick up "Surround" mixer for the rear output, and "Side" for the extra surround. Fix the channel mapping to follow it. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ALSA: ctxfi - Release PCM resources at each prepare callTakashi Iwai
The prepare callback can be called multiple times, thus it needs to release and acquire the resource again by itself at the second or later call. Simply add pcm_release_resources() at the beginning of each prepare callback in ctatc.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: ctxfi - Fix a typo in MODULE_LICENSETakashi Iwai

2009-06-02ALSA: ctxfi - Fix Oops at mmappingTakashi Iwai

2009-05-20ALSA: ctxfi - Add depends on X86Takashi Iwai
